TWISTINGMACHINE.

To all whom 'it may concern.'

Re it known that l, GUsTAvns A.. ANDER- noo, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in 'lwisting- Machines, oi which the following is a full, clear, concise, and exact description.

This invention .relates to twisting niachines, and more particularly to machines for the twisting of conductors for use in electric cables and like articles of manufacture.

The object of this invention is to provide a machine for twisting conductors in such a manner that the twisted conductors are of the` same length, whereby the electrical qualities of said twisted conductors are greatly improved when said conductors are used in electric cables.

The features of this invention are the 4 ineans provided for equalizing the speed at which the conductors travel throu h the twisting machine and-other details oi structure and combination of parts as will hereinaiter more clearly appear.

'.lhis invention is illustrated in the accompanying drawing in which the same reiE- erence characters are used throughout to designate the same parts, and in whichligure 1 is a frontelevation of a twisting machine embodying this invention, and

Fig. 2 is a view on lines 2-2 of Fig. i.

Reterringtothe drawing, 5 and 6 are side iraine members joined at top and bottom respectively by su porting plates 7 and 8. Mounted upon t e bottom supporting plate 8 is a revolving iianie com rising a shaft 9 carrying a bar 10 upon eac i end of which' is mounted a yoke 11. Mounted-upon the upper end of the shaft S) and hollow hubs 12, 12 of the yokes 11, 11 is an auxiliary in.- verted T-shaped frame 13, the upper end thereof being hollow and journaled in the upper supporting plate 7. The housing 14 contains the usual gears for driving a can stan 15 for drawing the conductors through. the revolving frame, said gears meshing with a gear on the upper end of the frame 13. Since the arrangement of the gcarsfor driving the capstan from the frame 13 is well known, it is not considered necessary to either show or describe them. volving frame is driven through the necesv Specification of Letters latent.

sary shaiting and gears from a aiiitahln motor-such as is shown at 20 in llita it. "l

ln order that the twisted conduct he properly wound on a receiving ree., are provided pedestals 21 and 2F?. in which is journaled ashait 523 which. carries a reel @it and is driven by means of a beit 26 pessima` over a pulley 25 carried by said shaft and over a pulley 27 carried by a shaft QB tween the motor 20 and the-revolving traina.A

To provide for the proper distribution of the twisted conductors on the receiving rech To nialce the two conductors 'traveloat the,

saine rate of speed through the twisting Innn chine, the vertical portion of the auxiliary inverted T-shapel 'traine is :formed into two (Fig. 2) joined at topand and 43 carrying at their outer ends short shafts 4G, 416 upon which are :mounted flat rimmed wheels ist, fil. These wheels fifi, have [hinges 45, d5 formed on caih edgaoit the periphery thereof.

Referring now to the operation of a twist `ing machine embodying the invention here inhefore described and illustrated in the acconipanying drawing, the spools containing the conductors to he twisted are mounted in a horizontal position in the yokes 1i, 11, as shown in Fig. l. lhe conductor .48 from the spool mounted in the yoke 11 at the left of the machine is led up through the hollow hub LZ thereof, up and over the lefthand wheel 44, down, under and then over the richt-hand `wheel 44 down and under the lett-hand wheel 44 (this cycle may be repeated two or three times), then assing from the left-hand wheel i4 into t e hol low end of the vertical portion o the auxu iliary inverted Tshaped.frame 1&3, and here is joined by the other conductor 49 which has followed a similar course frein the ri vh@ hand reel. The two conductors 48 an 49 now pass throu h the hollow end of the ver tical portion o the auxiliary 'inverted Tw them* distributer screw 239-' lit Vlili y sliaped frame 13 where they are twisted tolters, around "the capstan l several K andineily onto the receiving reel Fi/'hen gether due to rotation of the revolving frame and the forward movement of the conductunes the machine is started the revolving frame, wheel-s 44, 44, eapstan l5 and receiving ree f 24;l .to revolve, the Wheels 4%, iL/1L. being driven ley the conductors which pass around f ductor `in ,assin around. each of the wheels their peripheries. The action oi" each con 44, 44 eauses the equalization ot' the speed of ,ther conductors through the mechanism, Among the advantages ci? invention ale/ease 'withl which the few and simple iitsihey lhe assembled; no `ggvarts need he ,changed when diii'erent sizes ot conductors arje'to-betwisted and the Darts are so arthat the minimum amount of time iBfJ-iequired for threading up the machine i'eadyfor operatien.
